THE TROUBLED HISTORY OF THE DUCAL DOMAINS ON THE FRONTIERBETWEEN...

1175. The troubled history of the ducal domains on the frontierbetween Cornouaille and the BroeÈrec at this time synchronises perfectlywith the chronology of the foundation of the abbey of Notre-Dame deCarnoet.

This dislocation would have prevented wholesale reform ofthe administration in any event.Henry II may have reformed the administration of Cornouaille, as inNantes and Rennes, by introducing a seneschal whose duties extendedbeyond the ducal domain, but the evidence for this is very tenuous.

®rst-cousins, and the Boterel family held honour of Richmond land in Abington, Cambs., of the

Lanvallay family (R. Ransford (ed.),

The Early Charters of the Augustinian canons of Waltham Abbey,

Essex, 1062±1230, nos. 164, and 166). It is, therefore, possible that William de Lanvallay secured

Reginald's appointment. On the other hand, Reginald's family also had a history of service to

Henry II. His father attested at least one charter of Henry, as duke of Normandy, in 1149/50

(Actes d'Henri II, no.

x). Hamo Boterel (p. 210) may have been an uncle. Prior to 1181, Reginald

himself is only recorded in the service of Conan IV (EYC,

iv, nos. 30, 30A, 52, 55 and 58).

Henry wasnot a member of Conan IV's household, since Conan's charters weremore often attested by another seneschal, associated with Guingamp,Geoffrey son of Rivallon.

Henry may, therefore, have been `seneschalof Cornouaille', but whether he was accountable to Conan IV or HenryII is unknown.bailliesHaving discussed the government of Brittany under Henry II region-by-region, this is an appropriate point to discuss the theory that HenryII was responsible for the creation of the eightbailliesof Brittany.
